Title: Process for winning metals or metal alloys and also plant for carrying out the process
Inventor: OTTENSCHLAEGER ERICH
IPC: C21B11/02
Filed: 1987-10-23
Abstract: In the process, metals or metal alloys, in particular ferroalloys, are won by reduction of metal oxides in a reduction zone which is formed of a coal bed through which reduction gas flows. To obtain metals which possess a high affinity for oxygen, the coal bed is formed of three fixed bed layers (A, B, C), with provision of a bottom layer (A) comprising degassed coal and covering a liquid bottom zone comprising reduced metal (3) and slag (4). Furthermore, oxygen or an oxygen-containing gas is introduced into a middle layer (B) to form a hot reduction gas, and at a distance above this point finely divided oxidic starting material is introduced into the middle layer (B). Combustion gases comprising carbon particles and oxygen or oxygen-containing gas are introduced into a topmost layer C) (Fig. 1). <IMAGE>

Title: Device for sealing a wall through-passage of a pipe or the like
IPC: F16L5/02
Filed: 1988-03-07
Abstract: A description is given of a device for sealing a wall through-passage of a pipe or the like. The device exhibits a sealing body which is configured as an annular hollow body with an inner wall and an outer wall, consists of a compliant material and is formed approximately in the manner of a sleeve. The distance between the inner wall and the outer wall tapers from one end to the other. The cavity between the inner wall and the outer wall is configured in order to receive a plastically deformable sealing composition. From one end side, a sleeve-like pressing and clamping ring can be plugged in between the inner wall and the outer wall of the sealing ring. For sealing, the sealing body is plugged over the pipe which is to be sealed and the pressing and clamping ring is then pushed or driven further inwards into the sealing ring, such that the sealing composition thus escapes out of outlet openings and enters into the regions which are to be sealed.
